Application August 24, 1945, Serial No. 612,448

3 Claims.

My present invention relates to a combination section lining device fordrawing parallel lines to indicate sections in mechanical drawings.

The object of this invention is to facilitate by speed, precision,uniformity and ease, the drawing by a writing instrument of parallellines on a drawing to indicate a section.

To the above end, the invention consists of the novel construction andarrangement of parts hereinafter described and defined in the claims.

In the accompanying drawing, which llustrates the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a plan view of my reversible section lining device;

Fig. 2 is an end elevation of the same;

Fig. 3 is a fragmentary detail view in section taken on the line 3-3 ofFig. 1, on an enlarged scale; and

Fig. 4 is a view corresponding to Fig. 3 but showing a non-reversiblesection lining device.

The reversible section lining device shown in Figs. 1, 2 and 3 includesa relatively thin, rectangular frame 5 for a multiplicity of narrow,parallel ribs 6 that are integral therewith. These ribs 6 are laterallyspaced to leave narrow writing instrument passageways 1 therebetween. Asshown, the ribs 6 extend at angles of forty-five degrees, but, ofcourse, may extend at any desired angle. The ribs 6 are spaced inwardlyfrom each face of the frame 5 to leave a clearance space 8 for a pieceof paper or Bristol board lying on a table, not shown. In each endmember of the frame 5 is a paper passageway or slot 9 that branches andleads to clearance spaces 8. The clearance spaces 8 and the passageway 9extend the full distance between the side members of the frame 5.

From a medial plane between the faces of the frame 5, the sides of eachrib 6 converge to narrow upper and lower edges. This formation of theribs 6 materially reduces the Width of the passageways 1 at the wideportions of said ribs which guide a writing instrument. The upwardlydiverging sides of adjacent ribs 6 make it extremely easy to insert awriting instrument into the passageways 1. Also the downwardly divergingsides of the ribs 6 prevent ink from being drawn from a pen by capillaryattraction.

To place a piece of paper or Bristol board in the section lining device,the same is inserted endwise into the passageway 9 at one end of theframe 5 and directed into the lowermost branch of said passageway. Fromthe respective passageway 9, the paper is fed in the lower clearancespace 8 under the ribs 6 and into the passageway 9 in the other endmember of the frame 5. The paper under the ribs 6 will lie on the tableon which the section lining device rests and be held against transverseshifting movement by the side members of the frame 5. In placing thepaper in the section lining device, one end portion thereof is leftprojecting outwardly of the frame 5 so that said paper may bemanipulated in the section lining device. The ribs 6 are connected byseveral rows of reinforcing ribs IO. These reinforcing ribs IO areintegral with the ribs G and permit a writing nstrument to be placedthereover and thereunder to continue a line being drawn that wasinterrupted by one of said ribs.

Obviously, by reversing the section lining device, the inclination ofthe ribs 6 will be reversed.

The section lining device shown in Fig. 4 is non-reversible and partsthereof that correspond to like parts in Figs. 1, 2 and 3 are given thesame reference numerals followed by a prime.

The section lining devices are made of a transparent material.

From what has been said, it will be understood that the inventiondescribed is capable of modifications as to details of construction andarrangement within the scope of the invention herein disclosed andclaimed.

What I claim is:

1. A section lining device comprising a rectangular open frame having aplane face, the opposite ends of the frame having inwardly extendingslots, the outer ends of the inwardly extending slots being parallel tothe plane of the face and the inner ends of the slots diverging towardsthe plane of the face and terminating inwardly of the plane of the facefor feeding a sheet of writing material thereto; spaced ribs lyingwithin said frame, the edges of said ribs adjacent said face beingcoplanar and spaced from said face by an amount substantially equal tothe thickness of a sheet of writing material, whereby such sheet may beextended through said slots with a portion of said sheet lying betweenthe plane of said face and said rib edges.

2. A device as claimed in claim 1 wherein the frame has plane oppositefaces and the inner ends of the slots diverge towards both oppositefaces.

3. A device as claimed in claim 2 wherein the spaced ribs are beveledtowards both faces.
